-All you ever wanted to know about the 757 fuel system
http://www.smartcockpit.com/pdf/plane/boeing/B757/systems/0006/
The fuel wasn't leaking, it was venting from the surge tank NACA duct. The surge tank is normaly dry but if the main tanks get "Over full" the excess will flow through the vent gallery into the surge tank. The surge tank will contain a certain amount but if that gets full it spills out.
Because the report was taken from the gutter press I would ignore the "Thousands" of gallons bit! You would be amazed how a little fuel will produce a huge vapour trail!
Whilst it unusual to see this it is not dangerous.
During your trip to Turin there will be a flow of fuel vapour out of the NACA ducts when the aircraft is fueling and then there will be a flow of air back into the wing as you are flying.

-thanks Mr King
i was originally on the Man flight but the end of March departures got cancelled, i guess they would have be A320s
but now on the Gatwick one which i think will be 757
i have always loved their looks since i first saw one at Farborough 82 or 84:eek:

It seems from the pictures in the original link that the fuel was leaking further inboard than the vent from the surge tank. :confused:

-I saw some images of this and wondered what was going on! Thanks for the explanation, Cking, and the website you linked to is pretty damned cool!

-'The pilot immediately came on the tannoy and explained what was going on but some people were worried that because of the amount of fuel leaking there wasn't enough to get back to Turin
Too many HSE anoraks on the plane!
